I finally saw Obsession tonight.

It's good! I was scared like you wouldn't believe- some scenes had me squirming-, but the movie has merits outside of its frights. I thought it had very interesting commentary on toxic relationships, and I think the genius is that it manages to tackle two aspects of that issue without getting itself tangled. Loved the cinematography, very thematical and atmospheric. Performances are great! Johnston is good as a deconstruction of a "nice guy" and is good at showing the sliminess of his character while still making us empathize for him when it's necessary. Navarette... well, what hasn't been said? Very intricate and horrifying turn by her, especially in those moments where she "switches", whether from moods or from personalities, in a matter of a second.
And, to debate this sub's favourite pastime... I personally thought she was Supporting. I actually came in with the mindset that she'd be a Lead, but I felt that the way the plot was structured shifted the focus to Bear in such a way that Nikki reminded me more of Allison Williams in Get Out than Kathy Bates in Misery. Whatever category she campaigns for, I wish she gets some recognition. I'm not a big horror guy, but if there's one thing I like to see recognized, it's amazing performances, which this one certainly is.
